One of You Will Outlive the Other: How Does The Plan Hold Up When One of You Isn’t There?

There’s a piece of retirement advice going viral this week that could quietly wreck the next 20 years of your life.

And if you’re married, it could wreck the 20 years after that too.

You’ve probably seen it.

Money.com ran it Sunday. Yahoo. MoneyWise.

Every outlet with the same headline: retirees have been under-spending. You can safely spend 20% more.

Sounds like good news.

Except that advice only holds if two things stay true.

Your health. And both of you.

Nobody in the headlines is telling you what happens when either one of those changes.

The Sentence Nobody Quoted

I’m not here to alarm you.

But what good is advice if it isn’t honest with you?

If you’ve been reading those headlines and thinking “finally, permission to enjoy this,” I understand why.

You’ve spent 30 or 40 years saving.

You’ve built real wealth.

Most people never get there.

You’ve earned the right to enjoy it.

But I want you to hear this from someone who watched a two-person plan turn into a one-person plan in real time.

Years ago, I navigated my wife through terminal cancer.

Everything shifted at once.

Income. Taxes. Healthcare. Decisions I had hours to make, not months.

That’s why I read this new research differently than everyone else did.


Sounds Like Good News. It’s Not.

David Blanchett is one of the most respected retirement researchers in the country.

He just published new work on how retirement spending changes over time.

His finding: for most retirees, spending doesn’t rise at the end.

It drifts down and stays down. So the math says you can spend about 20% more early in retirement.

The headlines celebrated that.

Here’s what got cut.

Blanchett wrote, direct quote, that healthcare is “a clear wildcard” with “significant idiosyncratic risk.”

Academic language for a simple truth.

Some families get hit. Some don’t.

And nobody can tell you in advance which one you’ll be.

That’s the first wildcard. It’s the one Blanchett named.


The Wildcard He Didn’t Quantify

There’s a second wildcard he didn’t quantify, because it wasn’t what his paper was about.

It’s the day your retirement stops being a two-person plan.

That’s not a wildcard. That’s a certainty. One of you will outlive the other.

That’s not speculation. It’s math.

And the plan you built together doesn’t lose one person’s expenses. It loses one person’s income.

Here’s what almost nobody tells you about that day:

  • Your household loses one Social Security check. Not the smaller check added to the bigger one. The smaller one, gone. Permanently.
  • Your surviving spouse files single the next year. Tax brackets get cut roughly in half. The standard deduction drops from $32,200 to $16,100.
  • IRMAA, the income level where Medicare premiums start jumping, that threshold gets cut roughly in half too.

So your survivor can end up paying higher tax rates on lower income.

And possibly higher Medicare premiums on top of it.

Meanwhile, your mortgage is the same.

  • Property tax the same.
  • Utilities barely move.
  • Homeowner’s insurance the same.
  • Car insurance the same.

Here’s the number that I really need you to see.

Your survivor typically needs roughly 70% of your prior spending, but has about 64% of your prior income.

Sit with that gap.

Because that’s the gap most plans never test for.


Three Questions Your Advisor Probably Hasn’t Asked

I know that’s a lot. Take it in.

This isn’t meant to scare you. It’s meant to prepare you.

Here’s what I want you to do at your kitchen table this week.

I call it the One-Person Test.

Three questions. Answer honestly.

Not the answer you want. The answer that’s actually in your plan.

Question one.

What’s your household’s monthly income the day after one of you is gone? Do you know the number? Or have you never done that math?

Question two.

What tax rate does your surviving spouse pay on that income? Filing single. Tighter brackets. Smaller deduction. Lower IRMAA threshold. Does your plan account for all of that?

Question three.

Which expenses actually disappear when one of you is gone? Not the ones you assume, the ones that actually leave the budget. Housing stays. Utilities barely move. Property taxes are the same. Healthcare can even go up, because there’s no spouse to help with care at home.

If any of those questions stopped you cold, your plan works for two of you.

Not one.

Here’s the part your advisor probably didn’t tell you.

Most plans in this country are built for the joint scenario.

Because that’s what people ask about.

The one-person scenario is where planning gets hard, so it’s where planning gets skipped.


Why Most Plans Skip the Hard Half

This is why Step 4 of my Life-Tested Retirement System is called Life Season Mapping.

It’s not one plan for one retirement.

It’s a plan that runs both scenarios at the same time.

While you’re both here. And after.

Let me tell you what that looks like in practice.

A gentleman I’ve been meeting with recently.

61 years old. Sharp. Successful. His biggest concern wasn’t returns. It was income.

So I asked him: what income would your wife have if you weren’t here?

He stopped. He’d never done that math.

His previous plan hadn’t done it either.

Another household I worked with.

I’ll share this as an example, since every situation is different.

One spouse had a government pension. Great income for them, until the day it stopped.

Because the election they made at retirement, decades earlier, gave them a higher check while both were alive and nothing when one of them was gone.

That decision was irrevocable. Made once. Locked forever.

So we restructured around it.

Now the income exists for both scenarios. While they’re together, and after.


The Architecture Has to Already Exist

Here’s what I learned the hard way with my wife.

When her diagnosis came, I didn’t have days to reorganize the plan. I had hours.

The architecture had to already exist.

You cannot build it after the phone call.

That’s the difference between a plan you hope works and a plan that already knows what to do.


The Best Time Was Before You Needed It

None of this is about worst-case thinking. It’s about honest planning.

Blanchett’s paper is about which curve you land on.

But the real question, the one nobody’s asking, is which plan holds up when you become a one-person household.

Your plan has to work for both scenarios. Because one of them is coming.

If any of the three questions from the One-Person Test stopped you cold…

We’ll identify hidden vulnerabilities in your current retirement strategy – income, taxes, protection, and long-term sustainability, and determine whether your plan is built to withstand real-world disruption, not just ideal conditions.

You’ll leave with clarity on where your plan is exposed and what resilience-focused next steps look like.

The best time to build the architecture was before you needed it.

The second best time is right now.

Best regards,
